LII. On Salt Solutions and Attached Water. 

 By Frederick Guthrie. 



[Continued from p. 369.] 



Correlation between the Boiling and the Glaciation of Salt 

 Solutions. 

 § 139. ~T OOKLSTG upon the phenomenon of solution as being 

 -AJ brought about by the exercise of the force, physical 

 affinity, and regarding the act itself as being in the first instance 

 caused by the prevalence of what may be called physical adhesion 

 (as distinguished from mechanical) between the water and the 

 salt over the sum of the physical cohesions of the water and of 

 the salt, we must after the first contact (that is, when some of 

 the salt is dissolved) regard the contest as between the physical 

 adhesion between the salt and the solution of it on the one 

 hand, and on the other the physical cohesion of the salt toge- 

 ther with the physical cohesion of the solution of it. By an 

 increase of temperature the physical cohesion of the salt is les- 

 sened. By the solution of more salt the physical adhesion be- 

 tween the salt and the solution is lessened. Thus a partially 

 saturated solution so far resembles what some chemists call a 

 partially saturated atom, that it exhibits not necessarily a lesser
